AIR-GAUGIED FILLER VENT.

Application filed January 10, 1921.

To all whom it may concern:

Be it known that 1, Exam Benson Roan, a citizen of the United States ofAmerica, and a resident of the city of Portland, in the county ofMultnomah, in the State of Oregon, have invented certain new and use fulImprovements in Air-Gauged itiller Vents, of which the following is aspecification, reference being had to the accompanyin drawing.

/ly invention relates to filler-vents primarily adapted for supplyingair to pneumatic tires, for gauging the pressure of the confined volumeof air so supplied, and for utilizin at will the air supply for otherand in ependent purposes.

My present invention is in the nature of an improvement upon that setforth in my application for United States Letters Patent, No. 416,463,filed October 12, 1920,

' in so far as both inventions have certain features in common.

The principal object of my invention is to simplify the principle, theconstruction, and the mode of operation of m device. Other objects willappear to one s illed in the art upon perusal of the followingspecification, wherein what constitutes my invention is described indetail and is succinctly set forth in the appended claims.

In the accompanying drawin Figure I is a diametrical vertical section,partially in elevation, of my present invention in preferred form ofembodiment, the section being taken to include the gauge and air pipeconnection, and the parts being shown as if actuated by tire pressure.

Figure 11 isa view similar to Figure I showing the air valve in positionas if actuated to admit passage of air to a tire.

Figure 111 shows a part of the subject matter of Figure I, and attachedthereto a longitudinal section of a nozzle attachment. 1 Figure IV is abottom plan view of a portion of the subject matter of Figure 1.

Referring to the numerals on the drawing, 1 indicates the barrel of myfiller-vent that is provided on one side, with an internally threadedgauge socket 2 and an elongated pipe nipple 3. The longitudinal axes ofthe members 2 and 3 are parallel to each other and both are radial tothe longitudinal axis of the barrel 1.

The-longitudinal bore of the barrel 1 is preferably composed of sectionsa and 5 of Serial No. 488,284.

difi'erent diameters, the former being the one of smaller diameter.

The section 4: is disposed so as to make direct communication with thesocket 2 through-a duct 6 formed in the wall of the barrel 1.

The outer end of the section at is snugly fitted with a plunger 7 intothe inner end of which is threaded a tang 8 upon the end of a stem 9 ofsmaller diameter than that of the bore section 4: which surrounds it ontwo sides. Between the opposing ends of the plunger 7 and the stem 9 issecured an intermediate laterally projecting packing ring 10 which,through reciprocation of the plunger 7, serves to permit or to excludecommunication between the end of the duct 6 and the interior of the boresection 4.

Upon its end opposite the plunger 7 the stem 9 terminates in a valveactuating head which is preferably provided with oppositely disposedconical zones 16 and 17 and which fits loosely within the bore section 5An inclined passage way 18 through the head 15 penetrates the two walls16 and 17. The two bore sections a and 5 are separated at 19 by apreferably inclined annular wall, the angle of whose inclinationcorresponds substantially to that of the zone 16.

The shape of the zone 16 is only preferred for convenience of assemblingthe parts of the device, but the zone 17 performs, by reason of itsshape, an important function namely, that of actuating an air controlvalve 20, whose nose 21projects radially into the bore section 5 in thepath of movement of the actuating valve head 15, and which is snubbedback with valve opening efiect upon each reciprocation of the plunger 7and the stem 9 which is, in efi'ect, a continuation of the plunger.

The valve actuating head 15 with its attached plunger 7 is preferablyspring supported with reference to the barrel 1, or, in other words, thezone 16 is yieldingly urged against the wall 19. That efi'ect maybaconveniently arrived at through ,the employment of a coiled spring 25seated at one end Sigainst the valve actuating head 15 and surrounding aprojection 26 extending therefrom coaxially with the stem 9, the spring25 being seated at its opposite and against the top of a disk 27 bywhich the end of the bore section 5 is closed, except for the presencetherein of ducts opponte of the barrel 1, coaxially with and of greaterdiameter than the bore thereof. The wall of said cavity being internallythreaded, the

disk 27 being seated in the bottom of the cavity, is confined in placeby a threaded ring 31 screwed into the cavity against an intermediategasket 32. A stud 33 pro ects through the gasket 32 in the oppositedirection from the stud 29.

ll prefer to provide threads on the inside of the ring 31 to receive anozzle attachment 36, which, being provided with an inclined branchnipple 37, may be connected by a pipe td a source of liquid supply andmade to operate, by suction caused by discharge of air through it, todraw in liquid from said source of supply and to discharge it in a sprayfrom the end of the nozzle 36.

The efiect last described may be utilized to advantage about a garageand is made available in my filler-vent simply by provid ing it with themeans of connection for the attachment 36, as specified.

Reverting, now, to the description. of the air control valve 20, itremains to be specified that said valve is preferably provided with acoaxial stem 38 that terminates, at one end, in the nose 21 alreadyspecified, and whose other end is guided in its reciprocal movementthrough an aperture in a collar 40, threaded into the bore of the nipple3 and screwing into stop engagement with a shoulder 41. A coiled springdisposed about the stem 38 between the reverse side of the valve 20 andthe collar 40, serves yielding-1y to set the said valve upon its seat42. The part of the stem 38- between its nose 21 and the valve 20reciprocates loosely in a pas sage 43 between the bores of the barrel 1and the nipple 3, respectively. The com-- plenientary contours of thevalve 20 and its seat 42 serve to hold the nose 21 in place, while thedisplacement of the valve through engagement of the zone 17 and the nose21 of the valve stem 38 is so slight as to necessitate no otherprovision for its guidance than the conicity of the valve 20 and itsseat, respectively.

Into the open end of the socket 2 is screwed, with stiffening efiect, agauge case 45 within which, as upon a spacing collar 46, is confined agauge shell 47. A cylindrical gauge 48 works reciprocally within thespace between the gauge case 45 and the gauge shell 47, and is providedwith a head 50 which is laterally extended so as to serve as aprotective cap to the gauge cdse when closed against it.

To the inside of the head 50 is secured at i one end a rod 51 that isprovided at its other end with av piston head 52. The gauge shell 47 isinwardly flanged at its outer end, as indicated at 53, to afford a seatfor one end of a coiled spring 5% that is seated at its other endagainst the piston head 52, with the effect of .yieldingly confining thegauge 48 within its shell by a force measured by the power of the spring54. The outside of the gauge is provided as usual with graduation marksto indicate the relative degree of: compression of the spring 54.

It is to be noted that the nipple 3 and the gauge case 45 extend in thesame direction, that is rearwardly, from the'barrel'l. so as to afiord ahandle for in device that may be grasped by the hand 0 an operator. Whenso held, the plunger 7 may be conveniently depressedby any suitablemeans, as,

for example, by the thumb of the operator applied to a button 55 on theend of the plunger.

The following is a brief description of the operation of my device.

Assuming that the nipple 3 is connectedas by a flexible pipe, as it isin service, with a source of compressed air supply, the operator, whenhe wishes to use my device, applies the stud 33 to the ordinary fillingnip- .llf the degree of pressure indicated he ldwer than that desired,the operator, without further manipulation, simply depresses the lunger7. Thereupon the pee ring 10 first closes the duct 6, and, afterwards,the zone 17 of the valve actuating head 15,

by engagement with the nose 21, opens the valve 20, with the efiect of:aunicating air pressure through the ducts 28, A release at the plunger7 efi'ects immediate stoppage of compressed air supply, and restorescommunication between the ducts 28 and the piston head 52 with likeefiect as that already described.

By repeated operations of the plunger 7, if necessary, the tire pressuremay be brought to the desired degree as indicated by the graduations onthe gauge d8.

It is noted that whenever the valve 20 is opened by engagement between17 and 21, the duct 6 is closed by the packing ring 10, so that thedevice thereupon becomes, in effect, a simple air discharge outlet,controllable by manipulation of the lunger 7. It is becar e o th s eture that fp r o pro e5 ple of a tire, with the efi'ect of opening thevalve of the filling nipple. Thereupon, the

vide threads inside the ring 31, in order to accommodate the nozzleattachment 36, with the advantages of the uses derivable therefrom inthe manner already specified.

What I claim is:

1. In a filler-vent, the combination with a barrel provided with a bore,and a pressure gauge on said barrel organized to form gauge, of a pipenipple, an air control valve in said nipple having a nose extending intothe bore of the barrel, a plunger reciprocatory in said bore, a valveactuating-head actuated by said plunger into snub en agement with saidnose -for actuating the air control valve, and means operated by theplunger for controlling operative communicatlon between the bore of thebarrel and the gauge. 3. In a filler-vent, the combination with a barrelprovided with a bore, and a pressure gauge on said barrel organized toform a handle for the device, of a pipe nipple, an air control valve insaid nipple having a nose extending into the bore of the barrel, aplunger reeiprocatory in said bore, a valve head rovided with a conicalzone actuated by said plunger into snub engagement with the said nosefor actuating the air control valve, and means for operating theplunger. In testimony whereof, I have hereunto set my hand in thepresence of two subscribing witnesses.
